Coding agents — the kind that write tests, debug web apps, and automate browsers while simultaneously reasoning about a large codebase — have a context window problem. The existing solution for browser automation in agentic workflows is MCP, but MCP's approach loads verbose accessibility trees and large tool schemas directly into the model's context. When your agent is already holding thousands of lines of source code, test output, and reasoning, burning tokens on a full DOM dump for every browser interaction is genuinely expensive.
